Många processer i biologiska system utförs av maskinerier som är uppbyggda av molekyler av kolloidala dimensioner, d.v.s. i storleksordningen 1 μm till 1 nm, såsom proteiner. Dessa molekyler är ofta alldeles för komplexa till sin natur för att vi ska kunna förstå de “lagar” som styr hur de kommer samman för att bygga upp avancerade strukturer med biologisk funktion. I detta syfte behöver vi skapa The ability of microgels to adsorb to the interface of emulsion oil droplets has previously beenn reported in the literature.1 The resulting emulsions carry the thermoresponsiveness of the adsorbed microgels, and can be destabilized on demand by increasing the temperature above the volume phase transition temperature of the microgels. This thesis describes the synthesis and characterization of cro

Gymnadenia conopsea s.l., the fragrant orchid is widely distributed over Europe and adjacent parts of Asia. It is frequently found in open grassland, woodland and rich fen habitats, particularly in calcareous regions. The species is characterized by a high variation in morphological and genetic characters including plant height, floral characters, flowering time, habitat preferences, allozymes and

År 2006 var året då fler människor bodde i städer än på landsbygden och år 2030 uppskattas 5 miljarder människor bo i en urban miljö. Att lösa boendesituationen för de som flyttar till städer är ett globalt problem som kommer bli viktigare än någonsin tidigare att lösa. (Montgomery, 2014) Bostadsbyggandet i Sverige har de senaste åren ökat, men befolkningen ökar i ännu högre takt vilket gör att bo2006 was the year when more people lived in cities than in rural areas and by 2030 approximately 5 billion people will be living in an urban environment. Solving the housing situation of those who move to cities is a global problem that will become more important than ever to solve. (Montgomery, 2014) Housing construction in Sweden has increased in recent years, but the population is increasing at

Endowed with diverse vegetation covers, the Middle Atlas Mountains receive substantial snowfall in winter, which contributes to plant hydration during the growing season. Using remotely-sensed imagery, this study aims to assess the trends in snow cover variations between 2000 and 2015, analyse the local influence of snowpack persistence on vegetation growth and evaluate the significance of this ef

In developing countries across the world people are depending on rivers as a source of water for drinking, cooking and bathing. This is also the case in the Indonesian part of the island Borneo where this study was made. The largest river is the river Kapuas which, together with its tributaries, supplies the area with water. The hydrology of these rivers is changing and the quality of the water in

Antibodies have for long time dominated the field of affinity proteins in example imaging and therapeutics, due to their high specificity and affinity. However, they have some major drawbacks such as high molecular weight, complex structure leading to instability and high production cost. Therefore, other types of affinity proteins have been engineered, for example the Affibody molecule which is a

When an agitator is in commission for an extended period of time the impellers can become clogged. In order to clean the impeller, the agitator is runned backwards. This is one of the main functions for a product that CG Drives & Automation is developing for a customer in the agitator business. The purpose of this bachelor thesis is to develop and test this product for CG Drives & Automati

With growing awareness about their environmental impact, music festivals have increased their efforts to become greener since the 2000s. In line with this trend, the German Fuchsbau Festival developed a transport plan, taking into account that up to 80.0% of a festival’s emissions are produced through audience travel. Aiming at triggering a greener travel behaviour among its visitors, four measure

Sjögräs förändrar kemin under sig – betydelse för havets skogar att ta upp koldioxid Sjögräsängars betydelse för såväl den lokala vattenkemin som den globala koldioxidbalansen är väl känd, och de kallas ofta för havets skogar på grund av deras höga produktivitet och förmåga att lagra kol från atmosfären. Vad som dock händer under botten, i porvattnet bland sjögräsets rötter och dess associerade mSeagrass systems are integral components of both local and global carbon cycles and contribute to substantial modifications of seawater biogeochemistry which has ecological ramifications. However, the influence of the roots and rhizomes of seagrasses on surrounding porewater biogeochemistry is not fully understood, and it remains to be determined what exact role this marine plant and the associate

This study charts the possibilities of recycled plastic and its use as an alternative building material for low-income housing in Colombia. The building materials in the study have been compared with respect to their physical properties, the cost and how they affect the indoor climate in each building. Colombia is a country that has been subjected to civil war for many years, which has contribute

Water management tackles complexities within the interconnected social, political, economic and ecological systems across scales, while aiming to meet the needs of multiple stakeholders dependent on water. Many tensions and unsolved issues persist in water management regarding socio-political power structures, spatial scale, and relations between stakeholders who have different perceptions on prob

It can no longer be refuted that greywater reuse is paramount to curbing the persistent global water crisis. Of the domestic wastewaters, greywater is less polluted than blackwater, but treatment is still necessary to make it safe for reuse. The most common greywater reuse application is toilet flushing. However, the use of vacuum toilets in the Oceanhamnen project, covered in this thesis, means t

During migration birds are exposed to several challenges, one of these are the potential threat of getting oxidative stressed. Oxidative stress can be defined as when free radicals are produced in a vastly amount so antioxidants cannot detoxify them. This is the case at higher metabolic rate such as migratory flight, and probably during hyperphagia at stop-over. The aim of this paper was to invest

Antibiotika är en av de viktigaste upptäckterna under 1900-talet. Med antibiotika blev det möjligt att bekämpa och förhindra bakteriella infektioner. Ett växande och svårlöst problem är antibiotikaresistans. Detta projekt syftar till att hitta alternativ till klassisk antibiotika. Vi har arbetat med sialinsyra, en kolhydrat som återfinns på cellytan. De flesta bakterier tillverkar inte själva siaThe development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl

Att dika skogar till förmån för bland annat bättre tillväxt kan påverka och förändra faktorer som marktemperatur och markfuktighet vilka är de viktigaste faktorerna för markrespirationen och flödet av koldioxid till atmosfären. Markrespirationen svarar för huvuddelen av koldioxidflödet till atmosfären från ett markbundet ekosystem. Koldioxid är en viktig växthusgas och små förändringar av flödet kDitching forests in favor of for example better tree growth can affect and change factors such as soil temperature and soil moisture. Those are the most important factors for soil respiration and the flow of carbon dioxide (CO2) into the atmosphere. The soil respiration accounts for the major flux of CO2 to the atmosphere from the terrestrial ecosystem. CO2 is an important greenhouse gas and small
